LIGHTING FIXTURE.

A,.p1ication T (17] whom it may concern:

Be it known that I, PAUL hi. Ho'rcnnm', men ol the United States, residing at @hicae'o, in the county of Cook and State oi? Illinois, have irwented certain new and useful Improvements in Lighting l ixtur of which the following is a specification.

This invention relates to lighting fixtures for indirect electrical illumination, and particularly concerned with fixtures of the suspended type.

Suspended indirect lighting fixtures include a canopy, a bowl, a reflector, and a connection between the canopy and bowl :for sustaining the bowl from the *anopy as well as :lor conveying electrical current to and from the illuminating element or elements within the bowl. The usual construction of suspendeo fixtures, however, is such that unsightly connections are employed for holding the reflector within the bowl, thus precluding symmetry of design and relation of the parts in the fixture. l urthermorc, the ordinary construction of suspended fixture is such that access to the interior of the bowl is dillicult, and this interferes with cleaning of the interior oi the fixture. and likewise with removal of the reflector or the illuminating element when such is desired. The conditions recited particularly apply to those fixtu es in which a single lamp is em ployed as the source of light.

The present invention has as its primary object the provision of a lighting fixture which will overcome the objections above recited, its construction being such as to free the same from unsightly suspensory connections and at the same time permit access readily to be had to the interior ot the bowl, whether for cleansing purposes, removal or repair of the reflector held therein, or removal of the lamp employed with the fixture.

A further object of the invention is to provide a lighting fixture having novel and efficient means for holding the reflector within the bowl against displacement therefrom and to sustain the same free from con tact with the bowl.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the acfiled August 29, 1921.

Ruler-ring," in detan to the accompanying drawings, and more particularly to Figs.

thereof. the numeral desig- 1, 2 and Z; A nutes the canopy oi, the hcreindescribed fixture. Any approved construction of canopy may be used so that it is unnecessary to set forth the specific construction thereof. Extending downwardly from the canopy 10 is the chain 11 at the lower end of which is supported a socket shell 12 within which is disposed any approved form of interior socket 13 to which is applied a lamp l l as the illuminating element. As above indicated, the invention is par ticularly concerned with suspended fixtures in which a single lamp is employed as the illuminating element, although the invention is applicable to those forms of fixtures where more than one lamp is employed for this purpose.

At the exterior of the socket shell 12 and at appropriate points thereon, is a plurality of vertically disposed receiving sleeves 15. Preferably, these sleeves are formed integral with the shell 12. Arranged within each of the receiving sleeves 15 is the vertical extension of a supporting arm 16, the hori- Eli) zontal extension of which arm 16 projects in a radial direction, as clearly seen in Fig. 2. Any number of the supporting arms 16 may be employed, but three of the same are shown in the drawi and suiiicient for the purposes fc'or which. they are intended. The arms 16 are termed of metal and have a cer no degree of inherent resiliency. Their vertical extensions eld within the sleeves by fastening screws 17, and said arms may be adjusted -vertically within said sleeves so that the bowl of the fixture may be SUPPOIL'tQd at -varyingdistances from the shell 12.

The bowl is designated by "he numeral 18. This is formed preferably of opaque material, such as any desired. me and within said bowl 18 is disposed a reflector 19 of any approved construction. However, a prei'ered form of reflector is that of glass with a silver mirrored back to constitute the reflecting element thereof. @bviously, the reflector 19 partakes ot the gcneril configuration ot the bowl 1S.

lVithin the bowl l8, and spaced at suitable points around the same. is a pluralit 0t reflector holders 20. Each of ,d holders comprises a fastening clip 21. and a supporting clip 22. The fastening clip 21. has an upwardly extending flange which abuts against theinterior of the upper edge oi: the bowl 155. and is tastcncd thereto either by riveting, .iqiohweldingr, r other equivalent means. The fastening clip 21 has a centrally disposed slot at its inner edge ant this edge, at the end portions thereot is provided with downwardly extending; "flanges 24-. The supporting clip 22 ot aeh of the holders 1% has a T-shaped head 25 at its outer end designed to fit beneath the fastening clip 21 and to be euggapld by a fastening screw 26 fitted in the slot of the clip 21. The screw J3 th rehy effectually holds the fastening and support ing clips together, and slight adjustment between. the two may be eii'ected thereby. At the inner portion of the fa. ninp; clip 22 is an inclined engaging lip 27 against which the edge or"? the reflector 19 is adapted to rest, and between the T-head 25 and the engaging lip 27 is an. offset 28 haying a t-shaped slot 29 formed therein. The slot 29 is adapted to receive a T-shaped loclo inp; head 30 formed on the horizontal e tension of the supporting arm 16 which cooperates with the holder 20 and by the inherent resiliency of the arm 16 the locking head 30 is held within the offset 28 after the head has been introduced therein through the lhaped slot 29. This inherent resiliency ot the supporting arms 16 also has a tendency to draw the engaging lips 27 oi: the holders 20 towards the center ot the fixture and thereby passes the lips against the edges of the reflector la sup- 1MB arms relation IIUUPQY- l8 and the ieflector iii are s ing; do'wnwarr inee posiiion, the other two s1 a rins act-- ing as pivots upon which the be lthus may ior swing. This positions the bow ready access to the interior thereof. and the same thereby may be easily cleaned. the lamp may he removed and replaced. or the reilector may be withdrawn 1170M} the bowl. For the conyei'iient and detachable connec tion of the shell 12 to the chain 1 the former is provided at its upper end with a balldilae head 31 termed oi a pair of spaced between which is received the lower terminal ink oi the chain ill. These lugs have aligned perforations in which is fitted a connecting screw Eli) or the like by which the chain is detachably engaged and held bclwre'a'i said lugs 32, and on which the socket iivotally suspended. l ornied in the upper end of the shell 12, and in 00111 munication with the space between said lugs 32, is an elongated opening; I-h-i: through which the wires (not shown) leading from the canopy 10 to the socket are passed. The opening 34liornied at the time the shell 12 is made which preferably is done bv die casting.

n Figs. 5 and {3 is disclosed another to-rm ot the invention. in the main this torui is suhsiautialiy the same as that dis closed in Figs. l. :3 and 3. but the reflector holder is slightly modified in order to adapt the term. in Figs. 5 and h for use in smaller bowls or with smaller reflectors. The attaching cli .Z'l ot the cl'ian szed form is the same as the attaching clip in the other form, and it includes the, fastening screw 26 to hold the support clip 35 in position on the fastening clip. tut the Sllljpfilliillg' clip in the term illustrated in and (i is oi increased length and the cngagii'ig lip 36 extends downwardly from the inner end of the clip $35. at the point oi' joinder oi? the engaging lip 3b with the supporting}; clip 3:") a T-shaped slot 3"? is :toii'ined, and said slot receives the locking}; head 30 of the cooperating supportin l arm 16 in order to connect the arms with the re holders heino' anchored in the sup- 3 screw and of the two towns 0 porting clips 2.,

reflector holders easily may enter and leave the slots 2 in the relative movement oi the clips 21 and 23 oi the one form, and the clips 2i and 3.7 oi the other, or move along the slots 22 when adjustment of the clips and is effected.

In connection with the foregoing it will be observed that the holders it) perform the function not only of sup porting the reflector 19 within the bowl l3. but thy also constiute the means by which the supporting arms 16 are connected to the bowl l8. Inasmuch as the holders Ll) lie wholly within the bowl l8, and are positioned below the upper edge thereof, there no unsightly appearing connections, and the symine y of the fixtures thereby is enhanced. l urthermore, by engagement oi? the arms is with the holders 20 the inherent resiliency of said arms is exerted. to press the engaging lips of the several holders against the edges of the reflector so as to yieldingly support the latter within the bowl, and by reason of the horizontal extensions of the arms 16 lying above the edges of the reflector 19 the latter also is prevented from being displaced upwardly from the bowl until the arms 16 have been freed from engagement with the holders 20.

In assembling the hereindescribed fixture, it will be obvious that the reflector 19 is positioned on the holders with its edges in contact with the engaging lips 27. Each oi? the arms ii) is then extended outwardly so as to bring its locking head 30 into engagement with the T-shaped slot 29 of the cooperating holder 20. On release of holding pressure from the arm 16 its resiliency causes the same to spring baclnvardly and draw the locking head 30 into the slot 29. ll hen all of the arms 16 thus have been ongaged with tae holders 20 the reflector 19 will be supported properly within the bowl, and the bowl likewise will be held in suspended relation to the shell 12 and the lamp l-l carried thereby. To release the bowl and reflector from engagement with the arms 16 a reversal of the operation just described only is necessary, and if access be desired to the interior of the reflector or bowl, as previously explained, such may be had by simply releasing one of the arms 16 from its operating holder 20, whereupon the bowl may be canted downwardly, as indicated by dotted lines in Fig. 3 and access to its interior then efl'ected.
